A common error with beginner golfers is to get your left hand grip too much underneath the club, engrain the correct left hand position in the grip with the simple drill
Do not approach your chipping stance like a full swing stance, keep your feet close together, slightly open, weight on your front leg and shoulders square to the target, this set up clears your hips prior to the shot and puts more of the toe of the club flat on the ground
When the clubface rotates the heel becomes the leading edge of the club and makes contact first so practice making dollar bill divots to eliminate that clubface rotation
